Day3 : Datatypes

   Datatypes

There are two types of Datatype in Java one is Primitive and Other is non-primitive datatype. The following flowchart shows a subcategory of Datatypes.


Datatype Name + Size(In Byte) + Range:

  1. Byte - 1 Byte - Range: -128 to +127
  2. Short - 2 Byte - Range: -32,768 to +32,767
  3. Int - 4 Byte - Range: -2,147,433,648 to +2,147,433,647
  4. Long - 8 Byte - Range : -9,223,372,036,854,775,308 to +9,223,372,036,854,775,308
  5. Char - 2 Byte -  Range: 0 to 65535(UNICODE) 
  6. Boolean - 1Byte(8 bit) or 1 Bit - Actually It's size is dependent on JVM some JVM takes 8 Bit Or Some takes 1 Bit
  7. float - 4 Byte - Range: -3.4 * 10^38 to +3.4 * 10^38
  8. double - 8 Byte - Range: -1.7*30^308 to +1.7*30^308

Day2 : Compiling Java Program with Examples

The First Java Program  class Test {          public static void main(String [] args)               {                    System.out.println("Hello User");               } } Always Write class which you want to make, the first letter in capital letter like Test. Here public is access modifier, static   is   used for memory management mainly ,   void is Return Type, main() is method, String [] args is command line argument, System is predefined method, out is object refinement, Println is predefined method. Compiling Java Program To compile a java program we can command Javac having with following Syntax: Javac Name of the program   For Example : Javac Test.java Whenever we compile a java program the compiler generates byte code files and these byte code files have 3 special properties: The Extension of the byte code file is always class. There main is always same as name of the class defined by programmer. Number of byte code files is always equal to the number of class d

Day1: Introduction to Java and its feature

Image
Introduction to Java Java is one of the most popular programming platform available in the market today and from the last 26 Years it is amongst the top 5 programming language of the world. Symbol of Java Programming Language Following are the most important feature which have made Java so popular in the software world. 1-Platform Independent  Before we can understand the meaning of the platform independent we must first understand the meaning of the world platform. In the software world, the world platform in the environment in which a program runs. In simple words it is the combination of operating System and CPU. So windows + core i7 is one platform while Linux + AMD(Advance Microdevices) Athlon is another platform. Now being platform Independent means that a program compiled on one platform can be executed on any other platform without rewriting OR recompiling and java has this ability with the help of byte code and JVM . Whenever we compile a Java program, the java compiler neve

What does System.out.printf( "%-15s%03d\n", s1, x) do?

What does System.out.printf( "%-15s%03d\n", s1, x) do?   First   s1   which is formatted using   %-15s . The   %   means that what follows is an argument that will be formatted. Then follows a   -   resulting in left alignment.   15   fills the string up to a length of 15 characters (adding spaces at the end). Finally the   s   means, that you are formatting a string. Second  x  which is formatted using  %03d . Here the  0  is the fill character, meaning that, if necessary, zeros are added. The  3  is again the width, meaning the fill character  0  is added as many times as necessary to make it 3 digits long (this time at the beginning). Finally  d  means, that a integer is formatted. OR "%-15s" means that within 15 blank space, the String "s1" will be filled in the left. (fill in the blanks from the left) "%03d" means that within 3 0s, the integer"x" will be filled in the right.(fill in the zeros from the right). This can only be done
